More a ghost story than a spy caper, the episode begins when Briggs (Steven Hill) hires Arianna (Martine Bartlett), a real (?) psychic, to expose a phony (Donald Davis) who is controlling an important scientist (Beatrice Straight) by bringing her "messages" from her dead husband. At a seance the phony's powers seem impressive. But was the unrecognizable corpse killed in a fire really Zubrovnik? The main plot seems almost incidental, when Arianna senses that the dead man was actually a murdered local beekeeper, and the constant, angry buzzing heard outside the windows begins to make sense. She demands another seance. Rollin (Martin Landau) and Barney (Greg Morris) are on hand with a convincing projected "ghost." But when the power goes out it is up to Arianna speak for not one ghost, but two. The beekeeper has his rather gruesome revenge on the phony psychic and his assistant who murdered him (remember, beekeepers control smoke, too) and after Arianna delivers a message from the real (and really dead) Zubrovnik, his wife's eyes are opened. She promises to share her work only with the good guys and Arianna joins a rather shaken Barney and Rollin as they ride into the sunset.
